apio	d8e4489079	kernel: Make Thread::ip() and sp() const-friendly	2024-12-11 19:17:04 +01:00
apio	d05d6fad0b	kernel: Interrupt waitpid (even when SIGCHLD is pending) when other signals are also pending ... This fixes init not receiving the kill signal when running tests.	2024-12-07 13:15:58 +01:00
apio	42afef5ccb	kernel: Leave reaping to the reap thread ... This seems to fix previous problems. Apparently reaping a thread somewhat corrupts/replaces the calling thread's address space. I should've known there's a reason we do it in a separate kernel thread...	2024-12-07 13:05:38 +01:00
apio	dc766e1da7	kernel: Rework VFS access checking + add processes ... VFS functions now accept a single Process* pointer instead of credentials and groups. There is now a distinction between processes and threads Now to fix all the bugs... waitpid crashes the process with an NX error...	2024-12-06 21:35:59 +01:00
apio	7b2977a036	kernel: Use a mutex to allocate new posix timers for a thread	2024-11-23 20:02:34 +01:00

apio	3ad23eab21	kernel: Add support for supplementary groups (1/2) ... Adds support for supplementary groups internally in the kernel. No userspace support.	2023-11-22 18:49:40 +01:00

apio	4a654bf093	kernel: Handle OOMs better and without deadlocking ... Use a separate task to do it. Also fix a bug where the init thread would get no kernel stack ever since 5f698b477.	2023-08-17 20:14:33 +02:00
apio	e2a77bb3da	kernel+libc: Add pledge support	2023-08-12 21:38:25 +02:00

apio	0c873923e8	kernel: Make OpenFileDescription shareable	2023-07-30 11:33:46 +02:00
apio	fb08594a18	kernel: Separate FileDescriptors and OpenFileDescription ... Also, add a did_close() callback for OpenFileDescriptions losing all their references.	2023-07-30 11:33:06 +02:00
apio	11df5a2ec3	kernel: Use pid_t internally for process IDs ... This removes a bunch of casts between pid_t and u64, and makes more sense since pid_t is literally the data type for process IDs.	2023-07-26 21:32:00 +02:00
apio	546d900454	libc+apps: Start implementing POSIX-compliant termios.h wrappers around tty ioctls	2023-07-12 19:23:06 +02:00

apio	c599251d2a	kernel: Rename UserVM to AddressSpace ... This is a more appropriate name now that it does more stuff than allocate virtual memory. To be fair, the name was a bit awkward anyway. Should have been UserVMAllocator I guess.	2023-07-09 20:38:04 +02:00
apio	5e564e9ae3	kernel: Move Thread::self_directory to UserVM ... Since this is only used by user threads, UserVM is a convenient/related place to store the PageDirectory in a RAII manner.	2023-07-09 20:32:42 +02:00
apio	e9e7b22323	kernel: Separate a thread's page directory into two ... The self directory, and the active directory. The active directory is the one the thread is currently using, and the self directory is the one the thread owns. This lets us keep track of both, which fixes ext2 executables crashing the system.	2023-06-25 20:35:40 +02:00
apio	e60b2a3d2f	kernel: Move thread exit code into a separate common function	2023-06-19 12:33:25 +02:00

apio	42eb0a1d74	kernel: Freeze waitpid()'s calling thread until a child tells us it's done, instead of polling it every 10 ms	2023-05-04 23:03:31 +02:00
apio	4616997f5b	kernel: Store a thread's parent directly instead of its parent's PID	2023-05-04 22:58:04 +02:00
